LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 304,878, dated September 9, 1884.

Application filed August 9, 1883. (No model.) Patented in Germany February 11, 1881, No. 15,619.

To aZZ whom it may concern:

Be it known that I, JorrANN Wmuron, a subject to the King of Prussia, residing at Aachen Prussia German Em )ire have in- 2 7 1 2 5 vented certain new and useful Improvements his invention has reference to shuttles for looms; and the invention consists of a cast metal shuttle-shell having transverse bridges and abutments cast in one piece therewith, said bridges having dovetail seats for the I r 5 roller-frames, bobbin-spindle, and thread-eye,

which parts are further secured to the bridges by means of fastening-screws, as will more fully appear hereinafter, and finally be pointed out in the claims.

In the accompanying drawings, Figure 1 represents a bottom view of my improved loom-shuttle, and Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a longitudinal section of one end of the shuttle, with the roller and roller-frame in elevation, showing the connection of the roller-frame with the shuttle-shell on a larger scale.

Similar letters of reierenceindicate the cor-- responding parts.

0 In the drawings, A represents the shell of a lo0m-shuttle, which shell is made of malleable cast-iron, and provided with two transverse bridges, a a, that are cast integral therewith, each of the bridges having a dovetail 3 5 groove,a,on one side and a dovetail projection,

a on the other side. The inner sides of the walls of the shell A are provided near the ends of the same with inclined abutmcnts Z) b,which, in connection with the dovetail projections a 0 of the bridges a a, SGIXG to retain Ushaped rollerh-ames B. The transverse piece or base of each roller-frame B fits by a dovetailed groove on thcdovetail projection a of the bridge, While its beveled ends are retained 4 5 by the inclined abutments b b, as shown clearly in-Fig. 3. The roller-frames B B are further secured in their position by clamp-screws b, which pass through the bridges a, and take into screw-holes in the roller-frames. At its outer ends each roller-frame B is provided with bearings b for the shaft '1) of a roller,B, which projects below the bottom edge of the shell A. In the dovetail groove a, at the inner side of one of the bridges, a thread-eye, c, is inserted, and is secured therein by the same screw, 1), which holds the roiler-frameB at that'end of the shuttle. In the dovetail groove a of the other bridge a the dovetailed base of the bobbinspindle c is inserted, the bobbin being placed in position on the spindle in the usual manner, said'spindle being secured by the same screw, 7), that holds the adj acent roller-frame 13.

Between the rollers and the ends of the shuttle-shell suilieient space is left in which the waste from the warp and weft threads can collect without exerting a brake action on the rollers.

The advantages of this invention are that the shuttle-shell is cast .in one piece with the bridges and abutments, so that the rollerframes, the thread-eye, and the bobbin-spindle can readily be inserted and removed to be replaced by new ones when worn out.

Having thus described my invention, I claim as new anddesire to secure by Letters Patent- 1. A cast-metal shuttle, A, having transverse dovetailed bridges a a and abutments I) b, all cast in one piece, substantially as described.

2. The combination, with a shuttle-shell,A, provided with abutments I) b and with trans verse bridges a a, having dovetail projections a of roller-frames B B, means for securing said frames in place, and rollers BB, substantially as described.

. 3. The combination of a shuttleshell, A, having transverse bridges, said bridges having dovetail grooves at their inner sides, with the thread-eye c, bobbin-spindle, and fastening-screws b, substantially as described.

4. The combination of a shuttle-shell, A, having transverse bridges and abutments, said bridges having dovetail projections at one side and dovetail grooves at the other, with roller-frames secured to the bridges and abntments, rollers carried by said frames, 21 In testimony that I claim the foregoing as thread-eye and bobbin-spindle secured to the my invention I have signed my name in presinner sides of the bridges, and fastening-screws l enee of two subscribing Witnesses.

by which one roller-frame and the thread-eye JOHANN VAMIOH.

5 and the other roller-frame and the bobbin- \Vitnesses: spindle are attached to the respective bridges, J AMES T. DUBoIs, substantially as set forth. ELIsE BRAUN.
